[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a filter plate, ensures that when the waste water in the storage tank is initially filtered by the filter roller and discharged from the drain pipe, the waste water will be filtered again by the filter plate. This intercepts the waste in the water that could cause pipe blockage in the storage tank, solving the problem that when the waste water enters the storage tank, the filter roller inside cannot continuously filter all the waste water. As a result, when the waste water is discharged from the drain pipe, some waste will remain in the water, causing blockage in the downstream pipe connected to the drain pipe.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, this utility model provides a drainage device for municipal engineering, including a base plate 1, a water storage tank 2, a filter roller 3, a drive device 4, an inlet pipe 5, a drain pipe 6, and a sewage pipe 7. The four corners of the bottom of the water storage tank 2 are fixedly connected to the four corners of the top of the base plate 1. The right side of the filter roller 3 is movably connected to the right side of the inner wall of the water storage tank 2 through a shaft pin. The left side of the filter roller 3 extends through to the left side of the water storage tank 2. The bottom of the drive device 4 is fixedly connected to the left side of the top of the base plate 1, and the top of the right side of the drive device 4 is fixedly connected to the left side of the filter roller 3. The inlet pipe 5 is fixedly connected to the top of the water storage tank 2. The drain pipe 6 is fixedly connected to the front of the water storage tank 2. The sewage pipe 7 is fixedly connected to the bottom of the water storage tank 2. A filter plate 8 is fixedly connected to the inner wall of the drain pipe 6. A flow-through mechanism 9 is fixedly connected to the front side of the top of the inner wall of the drain pipe 6. An opening assembly 10 is opened on the rear side of the top of the drain pipe 6.

[0023] refer to Figure 3 The unblocking mechanism 9 includes a support plate 91. The top of the support plate 91 is fixedly connected to the front side of the top of the inner wall of the drain pipe 6. A motor 92 is fixedly connected to the back of the support plate 91. The output end of the motor 92 extends through to the back of the filter plate 8. A scraper 93 is fixedly connected to the output end of the motor 92 by bolts. The front of the scraper 93 is slidably connected to the back of the filter plate 8.

[0024] As a technical optimization of this utility model, by setting up a smooth flow mechanism 9, when the garbage water is discharged from the drain pipe 6, the motor 92 is started, and its output end drives the scraper 93 to rotate, so that the front of the scraper 93 is in close contact with the filter plate 8 and rotates to scrape off the impurities on the filter plate 8, so that the filter plate 8 remains unobstructed and the water can pass smoothly through the filter plate 8 and be discharged from the drain pipe 6, thereby preventing garbage in the water from continuously sticking to the filter plate 8 and causing the filter plate 8 to become blocked.

[0025] refer to Figure 1 and Figure 3 The opening assembly 10 includes an arc-shaped groove 101, which is opened on the rear side of the top of the drain pipe 6, and an arc-shaped plate 102 is slidably connected to the inner wall of the arc-shaped groove 101.

[0026] As a technical optimization of this utility model, by setting the opening component 10, when it is necessary to operate inside the drain pipe 6, the arc plate 102 can be slid along the arc groove 101 to open the top rear side of the drain pipe 6, which facilitates the connection, cleaning or maintenance of the scraper 93 and the output end of the motor 92 by the staff. After the operation is completed, the arc plate 102 can be slid back to its original position to close the opening and restore the original state.

[0027] refer to Figure 3 The output end of the motor 92 is provided with a square groove 11, and a square plug 12 is slidably connected to the inner wall of the square groove 11. The back of the square plug 12 is fixedly connected to the front of the scraper 93.

[0028] As a technical optimization of this utility model, by setting a square slot 11 and a square insert 12, when the user connects the scraper 93 to the output end of the motor 92 with a bolt, the square slot 11 and the square rod are used to initially connect the scraper 93 to the output end of the motor 92. Then, the bolts are used to fix the connection between them, thereby preventing the scraper 93 from slipping when the motor 92 drives the scraper 93 to rotate for a long time due to the connection of the bolts alone.

[0029] refer to Figure 3 Both ends of the arc plate 102 are threaded with wing bolts 13, and the bottom of the surface of the wing bolts 13 is threaded to the inner wall of the drain pipe 6.

[0030] As a technical optimization of this utility model, by setting the butterfly bolt 13, the arc plate 102 is fixedly connected to the drain pipe 6. Since the butterfly bolt 13 is easy to manually tighten, it is convenient for the user to quickly disassemble it, thereby improving the user's work efficiency.

[0031] refer to Figure 3 A sealing gasket 14 is fixedly connected to the inner wall of the arc groove 101, and the surface of the sealing gasket 14 is in contact with the surface of the arc plate 102.

[0032] As a technical optimization of this utility model, by setting a sealing gasket 14, when the arc plate 102 is installed into the arc groove 101, the sealing gasket 14 is deformed by the compression of the arc plate 102, filling the tiny gap between the arc plate 102 and the arc groove 101, thereby playing a sealing role and preventing water leakage.

[0033] refer to Figure 3 The front of the support plate 91 has a through groove 15, and there are several through grooves 15 distributed in a rectangular and equidistant manner.

[0034] As a technical optimization of this utility model, by setting the through groove 15, when the water flows through the drain pipe 6, the through groove 15 provides more channels for the water flow, reduces the obstruction of the support plate 91 to the water flow, and enables the water flow to pass through the area where the support plate 91 is located more smoothly, thereby improving the drainage efficiency.

[0035] The working principle and usage process of this utility model are as follows: First, connect the sewage pipe to the inlet pipe 5, then connect the drain pipe 6 to the downstream pipe. Next, start the drive device 4 to drive the filter roller 3 to rotate inside the water storage tank 2. This allows the wastewater to flow from the inlet pipe 5 into the water storage tank 2. Most of the waste in the water is then filtered by the agitation of the filter roller 3 and adheres to it. Subsequently, the water in the water storage tank 2 begins to drain out through the drain pipe 6. At this point, the waste in the water is filtered again by the filter plate 8 in the drain pipe 6. Then, start the motor 92, causing its output end to drive the scraper 93 to rotate. The front of the scraper 93 rotates in close contact with the filter plate 8, scraping away impurities on the filter plate 8 and keeping it unobstructed. This ensures that the water can smoothly pass through the filter plate 8 and drain out of the drain pipe 6, preventing residual waste from causing blockages in the downstream pipe connected to the drain pipe 6. This provides the advantage of auxiliary filtration.

[0036] In summary, this municipal engineering drainage device, by setting up filter plates 8, ensures that when the garbage water in the storage tank 2 is initially filtered by the filter rollers 3 and discharged from the drain pipe 6, the garbage water will be filtered again by the filter plates 8. This intercepts the garbage in the water that could cause pipe blockage within the storage tank 2, solving the problem that when the garbage water enters the storage tank, the filter rollers inside cannot continuously filter all the garbage water, resulting in some garbage remaining in the water when it is discharged from the drain pipe, which could cause blockage in the downstream pipes connected to the drain pipe.
